High density polyethylene.

PEAD is the most widely used resin for the manufacture of bottles. This material is inexpensive, impact resistant, and provides a good moisture barrier. HDPE is compatible with a wide variety of products including acids and caustics but not with solvents.

How are plastic bottles made?

Thermoforming consists of heating a plastic sheet such as PET and adhering it to a mold under pressure and vacuum. This causes its shape to be fixed in the foil, creating a bubble. With this industrial process, multiple thermoformed containers are produced, such as blisters, trays and many more types.

What is the raw material of the packaging?

Food and beverage containers, in relation to the raw materials used for their production, can be classified as follows: metal, glass, plastic, paper and cardboard and composites.

What characteristics does a plastic bottle have?

Translucent, flexible material that is compatible with substances including acids and caustics. For hermetically sealed products. PET. It has good chemical resistance, but does not provide resistance to extreme temperatures.

What are the chemical components of plastic bottles?

They are made up of gigantic carbon molecules, together with other elements such as hydrogen, oxygen, nitrogen or sulfur. The substances from which plastics come can be of mineral, vegetable or animal origin: • Of mineral origin, such as oil, coal or natural gas.

What are the chemical properties of plastic?

Plastics are synthetic chemical substances, called polymers, with a macromolecular structure that can be molded by heat or pressure and whose main component is carbon. These polymers are large groupings of monomers linked together through a chemical process called polymerization.

What are the properties of PET bottles?

Characteristics and properties of PET

    Excellent mechanical properties (resistant to wear and folding). Very good barrier to CO2 and acceptable to oxygen and moisture. High chemical resistance and thermal non-deformability. Transparent and crystalline, and admits some dyes. Lightweight.

What shape is the bottle?

1. f. Glass, glass, plastic or other material container, with a narrow neck, used to contain liquids.

What function does a bottle serve?

Plastic bottles are used in the commercialization of liquids in products such as dairy products, beverages or household cleaners. It is also used to transport powdery products or pills, such as vitamins or medicines.

What materials are used for the containers?

The structure of the packaging material can vary throughout the packaging portfolio.

    Paperboard. Cardboard is the main material of our cardboard packaging. … Polyethylene. The polyethylene protects from external moisture and allows the cardboard to stick to the aluminum foil. Aluminum foil.

What is the raw material to make the plastic?

Most of the plastics we use have a synthetic origin from petroleum. They are simple to manufacture and the processes involve a low cost. It is the petrochemical sector that is responsible for manufacturing polymers for the production of plastics.

What is the packaging material?

Today there are mainly 6 packaging materials, including paper and cardboard packaging, plastic packaging, metal packaging, glass packaging, wood packaging, and textiles.

How are plastic parts made?

There are several possible processes to manufacture plastic parts. These are: extrusion, blow molding, thermoforming, rotational molding, injection-blow molding or injection. Depending on the geometry and dimensions of the part to be manufactured, one process will be chosen as the most suitable or another.

How is plastic made explanation for children?

Plastics are synthetic materials obtained through polymerization reactions from petroleum derivatives. They are organic materials, just like wood, paper or wool. Plastics have different properties that allow them to be molded and adapted to different shapes and applications.

How is PET made?

Its production is carried out from oil, where the benzene fraction is converted into para-xylene through various refining stages. This is oxidized in the presence of catalysts until crude terephthalic acid is obtained, which in later stages will have to be duly purified.

What geometric shape does a plastic bottle have?

The main volume of 17 faces – five square and 12 hexagonal, identical faces – allow a large number of bottles to be regularly grouped in various configurations and eliminate the empty space between them.

What are the parts of a bottle?

Bottle Parts

    Lip. The flat, circular top surface of the neck finish. Sealing Surface. The part of the bottle that makes direct contact with the closure to form a seal. … Mouth/Aperture. … Head/Crown. … Thread. … Ring necklace. … Ring of Transfer. Tamper Evident Transfer Ring.

How is a glass bottle described?

The glass used in the manufacture of bottles is of the soda-lime type, where the differentiating characteristics of these containers are: the color, the type of applicable stopper-cap (on which the type of mouth to be used will depend), as well as the choice or not of protective capsules for its closure.

What is PET, what are its properties, its main uses and the advantages and disadvantages of using it?

The properties of polyethylene terephthalate are infinite, among which the following stand out: A material of great hardness and rigidity, which can be used in contact with food due to its non-toxic characteristics. A great transparency, although it also admits different loads of dyes.

What are the physical and chemical properties of plastics?

plastic properties

Plastics are groups of organic macromolecules, generally of synthetic origin, mostly waterproof, resistant, diamagnetic and good acoustic, electrical and thermal insulators, although they are not very resistant to very high temperatures as a whole.

What are the physical and chemical properties of polymers?

Physical properties of polymers

Being large molecules, the structure is generally amorphous. Remarkable plasticity, elasticity and mechanical resistance. High electrical resistivity. Little reactive before acids and bases.

How are the physical and chemical properties of polymers?

Its large molecular mass compared to smaller molecules gives it (polymers) unique physical properties including hardness, high elasticity, viscoelasticity, and a tendency to form amorphous and/or semi-crystalline structures rather than crystals.

What is the chemical compound of plastic?

Plastic is a lightweight, durable, cheap and easy to modify material. It is made up of polymers, which are large organic molecules made up of repeating carbon units or chains called monomers, such as ethylene, propylene, vinyl chloride, and styrene.
